Sonic is a high-performance EVM Layer 1. It uses a Proof-of-Stake DAG-based ABFT consensus for sub-second finality and high throughput, with the S token as its native asset.
Straight into the app: Swap S · Buy S · Get UCASH with S
Proof-of-Stake DAG (ABFT). Settlement on U.CASH is non-custodial: every payment moves on-chain, direct to a wallet you control. Confirmation policy for Sonic: Credited once the transaction finalizes on-chain, typically well under a second..

The setup is deliberately short. One wallet capable of holding Sonic and a little S for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.
The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in S, settling with sub-second finality blocks on Proof-of-Stake DAG (ABFT), which the preview itemizes per leg. Settlement is on-chain to the address you chose: Credited once the transaction finalizes on-chain, typically well under a second. on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform in the path.
The route runs on the aggregated DEX route, and atomicity is the property that matters: the approved number either happens in full or the transaction reverts with nothing moved but the attempt's gas. There is no resting state between legs where value sits in someone else's hands, and a route that misses your bounds simply fails clean, ready for a fresh quote. Cheap and loud beats silent and expensive as failure modes go.
